signor to The American Steel and Wire Com pany of New Jersey, a corporation of New Je sey I i i Application May 20,- 1937, Serial No. 14am 2 Claims. (01. 214-130) This invention relates to coil tilting devices, Journaled in one pair of the bearing supports 2 is and, more particularly, to those for transporting a shaft 3 upon which is pivoted a platform 4. a stack of coils from a horizontal to a vertical Extending from,. and rigidly affixed to, the disposition, and vice versa'. In its general as:- pla-tform s a p o s together pects, the invention ls'similar to that shown and p n a bifurcated coil engaging ram. Extenddescribed in U.- S. Patent No. 1,868,562, issued g downwardly from the platform upon the July 26, 1932, to Messrs. Chubb, Ralston and pp s s of the pivot shaft 3 therefrom, s a w m crank arm 6, by meansof which the platform 4 In the handling ofcol and associated ram are adapted to bemoved it is frequently desirable to transfer a stack of about the Pivot 3- such coils, en masse, from a buggy or a hook, In the other shaft bearings 2 is disposed a whereon the major axis of the stack is disposed fink shaft 7, to which is imparted rotary 1110* in the horizontal, to a position where the stack h by means of prime mover 8 through a reducaxis is disposed substantially in the vertical, in tlon geahumt and shaft o p gs in. order to permit a grapple, or other suitable mech- Extendlng h wcen the crank shaft 1 and the anism, to engage the same The mechanisms crank arm 6 1s a pitman l I, whereby the motion provided hitherto f r h purpose have been of of crank shaft 1 is utilized to oscillate the arm complicated and heavy construction, and have 6, to raise and lower platform 4 and associated not been adapted to receive stacks of coils from mm The l h of the crank arm 6, and the a hack; or hther medium, which suspends the thrust of the crank shaft 8, are preferably suchstack fr within. a that, when the, latter is moved through 180 of It is an object of the presentinvention to pro are, the wlll'be moved through of c. vide a simple, Sturdy device f r the purposes and its associated platform and ram 41 correoutlined above, "that willgbe of simplified cone e amount struction, and yet, which will operate with grea descnbvlhg the Operation of the ism, emcjency it will be assumed that a stack of coils I2 is at It is another object hereof to provide a coil P P9 av buggy, as wn in Figure 5. A handling mechanism that is adapted to receive -D h is disposed within t e a stacks of coils from hooks or othersuspensories. as also Shown in Figure and the stack is w the above objectsin View, a t lifted and conveyed thereby to a position subjects and advantages ancillary thereto, which I Stantially as is shown in igures 2 and 3. The will be brought out more fully hereinafter as th bifurcated ram 5 permits its entrance within the description proceeds, a f embodiment of coil in straddled relation to the hair-pin hook the invention is disclosed in the accompanying '3 and the CQils e oved by the latter until drawingsin which; the lead coil engages the near surface of the Figure 1 is aplan View th r f platform 4. At this point, the hair-pin hook 13 Figure 2 is a sectional elevation is lowered slightly to clear the end coil, and is line lI-II in Figure 1. withdrawn, leaving thestack supported on the Figure 3 is a fragmentary end view of th d bifurcated ram 5, substantially as is shown in vice taken from line III-III in Figure 2. Figure 3 After the hook l3 has been removed, Figure 4 is a fragmentary mid-sectional view the prime mover 8 is energized to move the crank corresponding 0 th t shown in Figure .2, i lilsshaft 1 through 180 of rotation, and, thus, to t at ne e v i parts p s in the vertical. reciprocate the pitman II to the position II d with a grapple in Positionto engage a stack shown in dotted lines Figure 2. This movement of the pitman moves the crank arm 6 substantially 90, and disposes the platform 4 and ram 5 in the horizontal and vertical, respectively. These latter parts, together with the stack of coils supported thereby, are then disposed substantially as is shownin Figure 4, in which posi tion any suitable grapple I4 is in position to engage the stack, and to strip it from the ram 5. Suitable webs I5 carried upon the coil supporting face of the platform 4 provide suitable spaces is of strip steel or wire,

taken along Figure 5 is a. schematic side elevational view of a conventional type of buggy with a conventional type of hair-pin hook in position to remove or to place a stack of coils thereon.

Referring more particularly to the drawings in which like reference characters refer to like parts throughout:

The coil tilting device is carried by any suitable base structure I upon which shaft bearing supports 2 are anchored in any suitable manner.

beneath the stack into'which the grapple hooks I6 may enter to engage the same.

The above cycle of operation may be reversed in order to transfer a stack of coils, with its major axis disposed in the vertical, to a position wherein its major axis is substantially in the horizontal, as is shown in Figure 5." In this case, the ram 5 is elevated to the vertical, as is shown in Figure 4, and the grapple i4 is permitted to rest a stack of coils thereabout on the platform 4. After the grapple has been removed, the ram may be lowered either by reversing the rotation of the crank shaft 1, or, more preferably, by permitting it to resume its rotary movement 180 until the ram with its load is disposed in the horizontal. Thereafter the hair-pin" hook may be employed to remove the stack to the desired place.

While I have shown and described a specific embodiment of my invention, I do not intend to be limited thereto, since many modifications may be made without departing from the scope of my invention as it is defined by the appended claims.

I claim: 7

1. A device for handling stacks of annular articles comprising a support, a pair of rains extending in substantial parallelism from said support,

arranged to rotate the crank arm substantially,

one-half the' number of degrees of are as that which the crank shaft is rotated.

2. A device for handling stacks of annular articles comprising a support, a platform pivoted a thereto, a bifurcated ram secured to said platform with its longitudinal axis substantially normal to the plane thereof, a lever for tilting said platform, a crankshaft for actuating said lever, the relation therebetween being that the latter is turned two degrees of are for every degree of are through which the former is rotated, and

, means on said platform adjacent the ram for providing marginal recesses between said platform and any load supported thereby.
